General Description
The MAX6061MAX6068 are precision, low-dropout, micropower voltage references. These three-terminal devices are available with output voltage options of 1.25V, 1.8V, 2.048V, 2.5V, 3V, 4.096V, 4.5V, and 5V. They feature a proprietary curvature-correction circuit and laser-trimmed thin-film resistors that result in a very low temperature coefficient of 20ppm/°C (max) and an initial accuracy of ±0.2% (max). Specifications apply to the extended temperature range (-40°C to +85°C). The MAX6061MAX6068 typically draw only 90µA of supply current and can source 5mA or sink 2mA of load current. Unlike conventional shunt-mode (two-terminal) references that waste supply current and require an external resistor, these devices offer a supply current t h a t is virtually independent of the supply voltage (8µA/V variation) and do not require an external resistor. Additionally, the internally compensated devices do n o t require an external compensation capacitor. Eliminating the external compensation capacitor saves valuable board area in space-critical applications. Low dropout voltage and supply independent, ultra-low supply current make these devices ideal for battery-operated, high-performance, low-voltage systems. The MAX6061MAX6068 are available in a 3-pin SOT23 package. o Ultra-Small 3-Pin SOT23 Package o ±0.2% (max) Initial Accuracy o 20ppm/°C (max) Temperature Coefficient o 5mA Source Current o 2mA Sink Current o No Output Capacitor Required o Stable with Capacitive Loads o 90µA (typ) Quiescent Supply Current o 200mV (max) Dropout at 1mA Load Current o Output Voltage Options: 1.25V, 1.8V, 2.048V, 2.5V, 3V, 4.096V, 4.5V, 5V o 13µVp-p Noise 0.1Hz to 10Hz (MAX6061)

Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
